PCGrate® Software Worldwide

Company History

Our company has a wealth of experience in diffraction efficiency modeling of various types of relief and phase gratings. The most important outcome of our 30 years' work was the advent of PCGrate®, a modeling tool for analysis and optimization of the absolute diffraction gratings efficiency by an accurate boundary integral equation method. Development of such sophisticated software became possible as a result of the multidisciplinary collaboration between many experts in the domains of theoretical physics, applied mathematics, and computer science.

All that time our team has been working in collaboration with world-leading manufactures of ruled and holographic diffraction gratings, as well as with governmental laboratories and private companies. The PCGrate (earlier known as ProGrate and PC Grate) team was the first to create commercially available, PC-oriented software for exact analysis and optimization of the efficiency of relief and phase gratings. In 1989 the first PCGrate worked well enough under DOS on a PC/AT (or even XT!) with only 640 KB of RAM.

Today optical engineers and scientists all over the world make use of PCGrate®-S(X)™ codes as a research tool to simulate spectroscopic and micro/nano-electronic & photonic systems.


Company History

Our specialists live in Russia, United States, Canada, and Germany. We implement a true international cooperation, regularly perform distributed project development via the internet, and partly place our R&D orders in well-established companies. We are open to any questions or proposals pertaining to related scientific research and software development. Our experts take active part in various international conferences/projects and publish many articles in prestigious scientific journals.

The prime object of our activity is to bridge the gap between theory and experiment for all types of gratings, and to provide researchers with more versatile tools and methods for increasing performance of the next generation of photonics devices. That also becomes possible owing to our collaborators from:

• NASA GSFC

• NRL Space Science Division

• Richardson Gratings of Newport Corp.

• Laurence Berkeley National Laboratory


PCGrate® Capabilities

PCGrate® programs enable the user to accurately solve periodic boundary value problems*, which describe the incidence of a light beam on the relief or phase diffraction grating, zone plate & rough mirror.

Various incidence light & grating shape calculus including:

- Non-planar incident waves and concave/convex grating shapes;

- Many-shaped, with non-conformal and non-function border profiles.



There are two types of solvers available in PCGrate®, i.e. Penetrating and Separating. The solvers have different behavior and mutually complementary capabilities for many difficult cases such as coated gratings with thin layers, randomly rough periodical or non-periodical structures, grazing incidence, and photonic crystals.

PCGrate® software also includes two separate applications:

• Refractive Index Editor is a tool for working with Refractive Indices Libraries. You can create new libraries, view their contents, edit them, and import/export them. It has a multiple document interface, i.e. you can open as many documents for editing as you wish.

• Border Profile Editor is a tool that enables you to edit the files that contain border profile functions of grooves.

PCGrate® Results


Our codes are indispensable for efficiency calculations in the following problems:

-The x-ray–EUV range and very small wavelength-to-period ratios.

- Echelles and grisms at diffraction order numbers ranging from low to very high (thousands).

- Taking rigorously into account periodical and random roughnesses of any kinds.

- Rigorously accounting diffuse light intensity (ghosts and scattering).

- Pulse compression and high conductivity.

- 1-D & 2-D photonic crystals and multilayers with rough and non-conformal borders.

- Very deep reflection and transmission grooves (aspect ratios up to hundreds).

- Non-planar incident waves and concave/convex grating shapes.

- Any polarization states and other fine peculiarities.

The codes are especially convenient and accurate for modeling with the real border profile function. An example of this type is the case of groove profiles determined by: an atomic-force microscope (AFM), a transmission electron microscope (TEM), a micro-interferometer, a stylus profilometer, and also by indirect methods like actual growth modeling, etc.
